Specification of Letters Patent. Patented Dee. 29, 1914.

Application filed January 16, 1914. Serial No. 812,384.

T 0 all whom it may concern:

Be it known that I, CHARLES J. NASH, a citizen of the United States, andresident of Chicago, county of Cook, and State of Illinois, haveinvented certain new and useful Improvements in Draft-Arms, of which thefollowing is a specification and which are illustrated in theaccompanying drawings, forming a part thereof.

The invention relates to draft arms for railway cars, and is animprovement on the draft arm forming the subject of my pendingapplication Serial No. September 12th, 1913.

The object of the present invention is to provide the draft'arm withmeans for bearing directly upon both of the vertical faces of a transomor bolster, in connection with means for resisting upward movement ofthe rearward end of the arm.

The invention is exemplified in the accompanying drawings, and ishereinafter described. a

In the drawings, Figure 1 is a side elevation of the improved draft armas applied to a railway car; Fig. 2 is a detail plan view of the centersills of a car'with the improved draft arms applied thereto, the latterbeing shown partly in section; and Fig. 3 is a view in perspective of atie and buffer casting applied to the rear ends of the draftarms proper.

'In the drawings, the center ."lls of a-car are represented at 10 and1.1, and the end sill thereof at 12.

The draft arm, generally represented by the numeral 13, is a casting,one being attached to each of the center sills and, to this end, beingprovided with a lateral flange 14 bearing against the bottom of the silland an upstanding flange 15 bearing against the inner face thereof. Eacharm is also provided with a pair of draft shoulders16, 17, forengagement by the usual followers of a draft gear, and in theconstruction illustrated the arm is provided with an aperture 18 betweenthe draft shoulders to accommodate the transverse rod of the Cardwelltype of gear. Each draft arm is also .provided with a rearwardly facingshoulder 19 for hearing against the body bolster 20 of the car, and

789,415, filed arm is substantially identical with that of.

my previous application. The present improvement consists in providingthe extension 21 with adepending lug 22 which bears against the rearwardface of the bolster 20, and a casting 23 which is applied and riveted tothe under faces of the extensions 21 of the two draft arms, bearsagainst a downwardly projecting lug 24 at the rearward end thereof, andalso bears against the rearward face of the bolster 20, the forward endof the extension being of sufficient depth to engage the lower portionof the bolster. The casting 23 is of sufiicient width to extend underthe sills 10, 11, to which it is secured by means of bolts 25, 26. Therear end of the casting is flattened and abuts against timbers 27located immediately below the two center Sills and which, in accordancewith the showing in my previous application, may extend'to the fartherend of the car and similarly engage the draft bers 27. The casting 23ties the two draft arms together and, bearing upwardly against thecenter sills, resists the tendency to upward movement and strengthensthe rearward extensions 21.

I claim as my invention 1. A draft arm for railway 'cars having ashoulder for abutting against the forward face of a bolster, andextension for arching over the bolster, such extension be ing providedwith a forwardly facing shoulder for engaging the rearward face of-thebolster, and a lateral flange for the attachment of a plate for engagingthe lower face of a car sill.

3. A draft arm for railway cars having a shoulder for engaging the frontface of a bolster, and a rearward extension for arching over thebolster, such extension having a shoulder for bearing against therearward face of the bolster, and a member bearing upwardly against therearward extension secured thereto by vertical attaching members andadapted to engage the rear face of v the bolster and. the under faces ofthe sills of the car.

4. A pair of draft arms for a railway car each having a rearwardextension for arching over a bolster of the car and. being provided witha depending lug, and a member secured to the arm extensions and adaptedmaaeeo to bear against the depending lugs r rearward extension forarching over tllQ bolster of a car, such extension lid-3i depending lug,and a member fittii tween such lug and the bolster.
